AI search trackers and SEO suites
These tools focus on what AI SEO is at the retrieval and citation layer (October 29, 2026 prices).
FoundByChat
FoundByChat tracks when ChatGPT's search finds, cites or rewrites your pages. It checks your questions with web search on every 2 hours as a user in the US (English) or the Netherlands (Dutch), recording "Found" and "Cited" status and usual position. It also lists the title and snippet for each page in ChatGPT's index. It emails you for "New in the index" or "Snippet changed", and for "No search results" when three checks in a row return no web results. The first check sets the baseline. Free to start (no password or credit card), it includes API keys and a free GEO audit (5/day, no account) that fetches pages as OAI-SearchBot, rebuilds the ~200-character snippet, checks robots.txt for OAI-SearchBot, GPTBot and ChatGPT-User, and scores pages out of 100. FoundByChat checks ChatGPT search only, without competitor tracking or a visibility score.

Questions
What is the cheapest AI SEO tool for tracking prompts?
FoundByChat is free to start for checking questions in ChatGPT search every 2 hours (ChatGPT search only, with no competitor tracking or visibility score). HubSpot AI Search Grader gives a free one-time snapshot across GPT-5.4 mini, Perplexity and Gemini. Among the paid multi-engine trackers compared here, Otterly.AI has the lowest monthly entry price at $29/month for 15 prompts across ChatGPT, Google AI Overviews, Perplexity and Copilot (October 29, 2026).
Why does ChatGPT not cite my website even if I rank on Google?
The free GEO audit checks bot protection, access for OAI-SearchBot (OpenAI's search crawler), and whether text is present in the HTML without JavaScript. Blocking GPTBot (OpenAI's training crawler) does not remove you from ChatGPT search. Check your rules for OAI-SearchBot, GPTBot and ChatGPT-User with our free GEO audit.
Which AI SEO tools track the most AI engines?
Semrush Enterprise AIO and Writesonic Enterprise each track 9 AI engines. Ahrefs Brand Radar's index covers Google AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini and Copilot, and custom prompts add Claude. Peec AI Starter lets you pick 3 active models out of 6.
